It’s always a source of pleasure to see that this little series of articles I wrote with lexicographer Kerry Maxwell on tricky areas of grammar consistently makes it to the most popular posts on Onestopenglish, even though they were written more than five years ago! The most popular one seems to be an article we did on American and British differences in grammar (an unusual area, since most materials focus on lexical differences for learners). There are over a dozen mini articles each with teaching ideas on areas of grammar such as articles, determiners, verb tenses and the noun phrase. All of these are, additionally, in the free section of Onestopenglish – YAY!
